The Buxtehude-Werke-Verzeichnis ("Buxtehude Works Catalogue", commonly abbreviated to BuxWV) is the catalogue and the numbering system used to identify musical works by the German-Danish Baroque composer Dieterich Buxtehude (c. 1637 – 9 May 1707).
It was compiled by Georg Karstädt and published in 1974 as Thematisch-Systematisches Verzeichnis der Musikalischen Werke von Dietrich Buxtehude.
The Anhang ("Appendix") adds 13 spurious and falsely attributed works.
The fourteen trio sonatas (BuxWV 252–265) were the only works published during Buxtehude's lifetime.
Buxtehude composed chorale preludes on the following hymns: The keyboard canzonetta in A minor, BuxWV 225, was found just before the publication and therefore could not be inserted in the catalogue properly.
